Benefits of technology

The patent describes an electronic device with a display region that has dummy elements on one side. These dummy elements help to make the display look even and improve its performance. To achieve a good display, it is important to make the display region flat. This is important because the dummy elements don't appear to cause any unevenness in the display and they help to maintain the flatness of the region around the display. This results in fewer display defects and allows for better microfabrication of wiring patterns.

Problems solved by technology

As a result, display performance and a lifetime of the electrooptical device may decrease in some cases.
For this reason, it is difficult to provide a large-sized semiconductor sensor between the display region and the signal output circuit such as the data line driving circuit.
In addition, since the plurality of first signal lines or the plurality of second signal lines extend in a region along a side of the display region, it is difficult to provide a large-sized semiconductor sensor.
